WASHER - LOCK (Mitsubishi MB30016000)

A damaged lock washer can allow threaded fasteners to loosen under vibration, leading to component separation. During assembly, a lock washer's split or toothed design resists rotation by biting into the mating surfaces. The catalog reference for this aftermarket replacement part is Mitsubishi part number MB30016000. This hardware washer type provides a plain mechanical function of preventing nut or bolt back-off. A concrete generic failure consequence is that a missing or worn lock washer may cause joint failure and unexpected disassembly. Keeping a lock washer in sound condition helps maintain clamp load in bolted connections. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.022 pounds.
